Coldfire Lite modified for use with Codewarrior 7.2 available for downloading!

[vier_kuifjes]

(cross-posted on the 68K/ColdFire® MPU forum)

I have made some modifications to Coldfire TCP/IP Lite to make it compatible with the new Codewarrior 7.2. These modifications were necessary because CW7.2 can only use register parameter passing to functions while CF Lite was designed to use stack based parameter passing to functions.

I have found one issue though. When the optimisation of the compiler is set to >1, the TCP protocol fails to work. UDP on the other hand works fine on any optimisation level.

When this version of Coldfire Lite is compiled on CW7.1.2 (using register parameter passing), everything keeps working fine at every optimisation level.

This makes me believe there is an issue with code optimisation in Codewarrior 7.2.

For those interested, the new Coldfire Lite is available here:

Hi Marc,

I'm developing an application based on the Coldfire Lite modified for use with Codewarrior 7 and its fine.

I noticed there is an ethernet bootloader inside the source code...

do you have a mcp project with a bootloader for the Coldfire Lite modified for use with Codewarrior 7?

or could you suggest me where to find it?

thank you again,

Maurice

Hello Maurice,

It's been a while since I have used Coldfire lite, I switched to FNET for my application.

I have never used the boot loader and I have no modified version of it. But I don't think it shoud be too difficult to adapt the code to Codewarrior 7.2.2.

The most important thing to do is to replace the original files that contain assembly code with the new ones.

I'll see if I can take a look into it.

Regards - Marc

that would be great!

thank you

Hi Marc,

thanks for the Coldfire Lite modified for use with Codewarrior 7.2...

I noticed you have switched to FNET...

could you please post also a project with FNET for the M52233DEMO board?

@ FNET I found only a project for M52235EVB and I don't know how to adapt it to M52233DEMO board....

thank you a lot!

Maurice

Hi Maurice,

There's no need to adapt FNET to the 52233demo board. Just use the 52235evb version, it runs just fine on the demo board. Works for me! :smileywink:

Hi Marc,

thank you for your reply...

I compiled FNET Shell and Shell_boot and it worked!  :smileyhappy:

Then I tried to compile boot project and I found this error:

illegal constant expression

fapp_mem.c line 76  {"FNET Params", FAPP_FLASH_PARAMS_ADDRESS, FAPP_FLASH_PARAMS_SIZE},

C:\FNET 2.6.2\fnet_demos\common\fnet_application\fapp_mem.c

(CW 7.2, C:\FNET 2.6.2\fnet_demos\mcf52235\boot\cwcf7.2\m52235evb_boot.mcp)

do you have the same error?

thank you for support,

Maurice

All demo apps appear to compile fine here (FNET 2.6.2, Codewarrior classic 7.2.2).

Can you do to available your patched CF-Lite project?

Thank you very much for your help!

Hello Marc,

Thanks

Hello guys,

Sorry for not getting back to this any earlier. It's been a while since I have been active on this forum...:smileyblush:

I once uploaded the modified CF Lite as an attachment to one of my messages but apparently attachments aren't possible anymore now. I have made a download link available of my most recent version, which is now about 2 years old. I'm no longer using CF Lite anymore myself, I switched to using FNET.

Here's the link:

I hope this helps!

[diegoalonso]

Thak you very much Marc.

I proved and its works perfect. So i can use the debugger, that not works in cw7.1.

Hi Marc,

thanks for the Coldfire Lite modified for use with Codewarrior 7.2...

I'm trying to use the udp_client_example, but I'm a bit stack on how to compile it and run.

HTTP_WEB_SERVER works fine, and I would need to integrate udp in there.

I can not find any example to include the udp function in the main code.

I went in to the code that uses the task for the socket handle, but I don't know how to init udp in the main.c

I just need to implement udp send and udp receive...

thank you a lot!

Maurice
